Can someone help me with this please?

Answer:

y=70°

z= 60°

w= 70°

Step-by-step explanation:

Since the two triangles are similar, we know that all of the corresponding angles must be the same.  On the triangle on the left, we can see that the angle formed between sides AB and AC is 60°.  This means that the same angle is formed at Z, which is in the same location on the triangle to the right.  From there, we can find the missing angle, W, from the difference of 180°.

180°-50°-60°=70°.

The same way we found Z, we can also find Y, since it has to be the same as W.

A farmer plows a corn field in the shape of a rectangle that has an area of 15840 square yards if the length of the field is 132
igomit [66]

Answer:

<u>Width= 120</u>

<u />

Step-by-step explanation:

We know that <u>L*W= A</u>

So lets put in the variables we know into the equation.

<u>L= 132 yards</u>

<u>A= 15840</u>

132 * W= 15840

All we need to do is <u>divide 15840 by 132</u>

<u>15840/132= 120</u>

<u>W=120</u>

In order to help identify baby growth patterns that are unusual, we need to construct a confidence interval of the mean head cir
sukhopar [10]

Answer:

The 99% confidence interval estimate of the mean head circumference of all 2-month-old babies is (40.18cm, 41.02cm).

Step-by-step explanation:

Our sample size is 100.

The first step to solve this problem is finding our degrees of freedom, that is, the sample size subtracted by 1. So

df = 100-1 = 99.

Then, we need to subtract one by the confidence level \alpha and divide by 2. So:

\frac{1-\alpha}{2} = \frac{0.01}{2} = 0.005

Now, we need our answers from both steps above to find a value T in the t-distribution table. So, with 99 and 0.005 in the t-distribution table, we have T = 2.626

Now, we find the standard deviation of the sample. This is the division of the standard deviation by the square root of the sample size. So

s = \frac{1.6}{\sqrt{100}} = 0.16

Now, we multiply T and s

M = Ts = 2.626*0.16 = 0.42

For the lower end of the interval, we subtract the sample mean by M. So the lower end of the interval here is

L = 40.6 - 0.42 = 40.18cm

For the upper end of the interval, we add the sample mean and M. So the upper end of the interval here is

L = 40.6 + 0.42 = 41.02cm

So

The 99% confidence interval estimate of the mean head circumference of all 2-month-old babies is (40.18cm, 41.02cm).
